  "text": "Competent authorities shall evaluate the possibility of exposure of aquatic organisms to the plant protection product under the proposed conditions of use; if this possibility exists they shall evaluate the degree of short-term and long-term risk to be expected for aquatic organisms after use of the plant protection product in accordance with the proposed conditions of use.\n(a)This evaluation shall take into consideration the following information:\n(i)the specific information relating to the effects on aquatic organisms as provided for in the Annex to Regulation (EU) No 544/2011 and the results of the evaluation thereof;\n(ii)other relevant information on the active substance such as:\nsolubility in water,\noctanol/water partition coefficient,\nvapour pressure,\nvolatilisation rate,\nKOC,\nbiodegradation in aquatic systems and in particular the ready biodegradability,\nphotodegradation rate and identity of breakdown products,\nhydrolysis rate in relation to pH and identity of breakdown products;\n(iii)all relevant information on the plant protection product as provided for in the Annex to Regulation (EU) No 545/2011 and in particular the effects on aquatic organisms;\n(iv)where relevant, other authorised uses of plant protection products in the area of envisaged use, containing the same active substance or which give rise to the same residues.\n(b)This evaluation shall include:\n(i)the fate and distribution of residues of the active substance and of relevant metabolites, breakdown and reaction products in water, sediment or fish;\n(ii)a calculation of the acute toxicity/exposure ratio for fish and Daphnia. This ratio is defined as the quotient of respectively acute LC50 or EC50 and the predicted short-term environmental concentration;\n(iii)a calculation of the algal growth inhibition/exposure ratio for algae. This ratio is defined as the quotient of the EC50 and the predicted short-term environmental concentration;\n(iv)a calculation of the long-term toxicity/exposure ratio for fish and Daphnia. The long-term toxicity/exposure ratio is defined as the quotient of the NOEC and the predicted long-term environmental concentration;\n(v)where relevant, the bioconcentration in fish and possible exposure of predators of fish, including humans;\n(vi)if the plant protection product is to be applied directly to surface water, the effect on the change of surface water quality, such as pH or dissolved oxygen content.",
